Did you have one glass of wine or two? While the Breathometer can’t keep track of your drinks per se, it can give you an idea of how much alcohol is in your system. Set up is simple: Download the included app, plug the device into the headphone jack on your smartphone and blow into the device. The device will then provide an estimate of your current blood alcohol level. And if you’ve had one too many, it even has a link that can help you call a cab. Designed to work with compatible iPhones and Android devices, the Breathometer costs about $50. Of course, it goes without saying that if you feel the need to check to see if you can safely drive, you already know the answer.

With warmer weather comes the temptation to turn on the AC, even though doing so is sure to boost your electrical bill. One solution is to use a smart air conditioner that keeps an eye on both your home’s temperature and your budget. Consider the Aros, an 8,000 BTU window unit that powers itself down when you leave and turns itself back on in time to reach your preferred room temperature when you return. Based on your schedule, weather data, past usage and budget, it will even let you know if you’re in danger of going over your preset spending limit. Want to change a setting from afar? You can do so via a WINK app. Capable of cooling up to 350 square feet, the unit from Quirky costs about $300.

The JBL Synchros S400BT headphones make a great option for forgetful Bluetooth fans. When the headphones are charged, they wirelessly stream crisp audio from your favorite Bluetooth device. When the headphone’s rechargeable battery runs low, you can continue listening via the included audio cable. Designed with a stainless steel headband and comfy earpads, the sturdy headphones have a touch sensor on the left earcup, so you can quickly adjust the volume, switch tracks and accept a call with a swipe of the finger. When you’re ready to give your ears a rest, the headphones can be folded up and put in a handy zip-up case. The sweet-sounding headphones cost about $230.

Want to keep your kids away from your pricey – and loud – headphones? Let them try on a pair of HeadFoams, headphones made from a single piece of sturdy but soft and bendable foam. Designed for children ages 3 and up, the headphones from Marblue deliver audio at levels that are safe for young ears with a maximum decibel level of 85. Available in purple, blue and orange, the headphones cost about $40.
